Description

Technical Field

[0001] This utility model relates to the field of light control system technology, and in particular to optical components and optical devices. Background Technology

[0002] In the field of commercial lighting, downlights, spotlights, track lights, and other lighting fixtures are widely used. Among them, the optical components of commercial downlights play a crucial role. Through precise design, they can achieve accurate light control, high energy efficiency, comfortable visual experience, and scene adaptation, making them a core element in improving the quality of commercial space lighting.

[0003] Currently, the optical component fixing methods used in similar products on the market have some drawbacks. Existing products typically fix the anti-glare cover to the lamp body using clips on its back, and the optical lens is fixed to the optical lens bracket using clips, thus securing the optical components. However, this structure has revealed many problems in actual use:

[0004] 1) Cumbersome component replacement: If the optical structure needs to be replaced, the anti-glare cover must be removed first, then the optical lens must be removed, and the components must be replaced one by one. The operation process is complicated and time-consuming.

[0005] 2) Appearance is affected: The existing anti-glare cover has a buckle structure on the back. When the anti-glare cover is made of transparent material, the buckle on the back will be visible, which seriously affects the appearance of the entire lamp. Therefore, the existing anti-glare cover cannot be made of transparent material.

[0006] 3) The existing product structure limits the anti-glare cover to be embedded in the lamp body and cannot be installed externally, which to some extent restricts the design and application flexibility of the lamp. Utility Model Content

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] like Figures 1 to 6 As shown, this embodiment provides an optical assembly, including an anti-glare shield 100, a reflector cup 300, and an optical lens 200. The anti-glare shield 100 has an anti-glare structure 110 and an assembly structure 120, with the assembly structure 120 located at the bottom of the anti-glare structure 110. The reflector cup 300 is used to reflect light upwards, and the top of the reflector cup 300 has an upward-opening receiving groove 310. The optical lens 200 is located in the receiving groove 310, and the assembly structure 120 is detachably connected to the top of the reflector cup 300, so that the bottom of the receiving groove 310 and the bottom of the anti-glare structure 110 clamp the optical lens 200 from both sides in a vertical direction.

[0038] The optical assembly is composed of an anti-glare shield 100, an optical lens 200, and a reflector 300. It is detachably connected to the top of the reflector 300 via an assembly structure 120, allowing the bottom of the receiving groove 310 and the bottom of the anti-glare structure 110 to vertically clamp the optical lens 200 from both sides. This structure achieves a unified assembly of the anti-glare shield 100, optical lens 200, and reflector 300, ensuring stable connections between components and facilitating the manufacturing of the optical assembly. Simultaneously, the stable clamping method ensures the fixed position of the optical lens 200 during use, reducing changes in optical performance caused by loosening or displacement, ensuring normal propagation and refraction of light within the optical assembly, and guaranteeing the stable optical performance of the entire assembly. The assembly structure of this optical assembly is a modular design. When the optical assembly is damaged or requires replacement of optical components according to different needs, only the entire optical assembly needs to be replaced, simplifying the operation and enabling rapid replacement of optical components, thus improving the user experience.

[0039] Since the reflector cup 300 is designed with a receiving groove 310 to accommodate the optical lens 200, there is no need to design a structure on the optical lens 200 to meet the adaptation requirements. Therefore, the influence of the overall structure of the optical component on the optical lens 200 is reduced. As a result, in this embodiment, the assembly requirements of the optical lens 200 and the reflector cup 300 can be met simply by placing the optical lens 200 into the groove of the reflector cup 300.

[0040] In this embodiment, the assembly structure 120 is connected with a plurality of fasteners 121, and the bottom of the receiving groove 310 is recessed with a slot 311. The number of fasteners 121 and slots 311 is the same, and each fastener 121 is engaged with a slot 311.

[0041] The snap-fit ​​component 121 of the assembly structure 120 engages with the snap-fit ​​groove 311 at the bottom of the receiving groove 310, providing a simple and reliable connection between the anti-glare shield 100 and the reflector 300. This eliminates the need for complex tools or additional fasteners, reducing assembly difficulty and cost. This connection effectively prevents relative displacement or loosening of the anti-glare shield 100 and the reflector 300 due to vibration or external forces during use, ensuring the structural stability of the optical components and thus guaranteeing the stability of optical performance. Furthermore, it allows for convenient disassembly and assembly of the optical components when needed, further optimizing the assembly structure and making it easier to operate. It also facilitates the replacement of optical components, further demonstrating the advantage of quick optical component replacement.

[0042] For example, the anti-glare structure 110 is made of a light-transmitting material.

[0043] The anti-glare structure 110 is made of a light-transmitting material, allowing light to pass through and ensuring that the optical components can perform their lighting or optical functions normally. When the anti-glare shield 100 is made of a light-transmitting component, on the one hand, it can reduce light loss during transmission and improve light utilization to meet the requirements of light penetration in different scenarios; on the other hand, the light-transmitting anti-glare shield 100 can expand the application scenarios of the optical components, allowing them to blend with the appearance of other components or create unique visual effects through different light transmission characteristics, thereby enhancing the aesthetics of the optical components. For example, in places with special requirements for light transmission and appearance, such as art exhibitions and high-end shopping malls, the light-transmitting anti-glare shield 100 can better meet the needs.

[0044] In this embodiment, the fastener 121 is provided on the assembly structure 120, so that there is no need to provide a connector on the anti-glare structure 110, which helps to improve the overall appearance of the anti-glare structure 110 and helps to improve the lighting effect of the light-transmitting anti-glare cover 100.

[0045] In this embodiment, the anti-glare structure 110 is transparent. In other embodiments of this embodiment, the color of the anti-glare structure 110 can be white, black, electroplated silver, electroplated black, or other colors. The color of the anti-glare structure 110 is determined by those skilled in the art based on actual engineering conditions; specific and simple methods are common knowledge in the art and will not be elaborated upon here.

[0046] Furthermore, the anti-glare structure 110 is tubular, and the outer wall of the anti-glare structure 110 is provided with a textured layer 111.

[0047] The anti-glare structure 110 has a textured layer 111 on its outer wall, which enhances the refraction of light. On the one hand, the textured layer 111 can refract the light inside the anti-glare shield 100 back, reducing light scattering and loss and improving the light energy utilization of the optical component; on the other hand, the textured layer 111 can increase the visual layering and three-dimensionality of the optical component, improve the overall appearance of the optical component, and make the optical component more aesthetically pleasing and unique, thereby meeting the personalized needs of different users for the appearance of the optical component.

[0048] In this embodiment, the assembly structure 120 is annular, and three fasteners 121 are provided and are evenly distributed at intervals on the outer periphery of the assembly structure 120.

[0049] Specifically, the anti-glare structure 110 is coaxially arranged with the assembly structure 120, and the bottom end of the anti-glare structure 110 is fixed to the edge of the inner periphery of the assembly structure 120.

[0050] In this embodiment, the inner diameter of the anti-glare structure 110 gradually increases from bottom to top.

[0051] The above structural design can diffuse and guide light to a certain extent, optimize the propagation path of light, improve the utilization efficiency of light, enable light to be distributed more evenly in the surrounding environment, avoid excessive light concentration or the formation of dark areas, improve the uniformity of lighting effect, and enhance the optical performance of optical components.

[0052] This embodiment also provides an optical device, including a fixed bracket 410, a light source 420, a protective component, and the aforementioned optical components. The protective component has a mounting groove. The fixed bracket 410 and the light source 420 are fixed to the bottom of the mounting groove. The fixed bracket 410 is detachably connected to the bottom of the reflector 300, so that the light source 420 extends into the reflector 300. The light source 420 is used to emit light.

[0053] This optical device, composed of a fixed bracket 410, a light source 420, a protective component, and optical components, forms a complete lighting system. The light source 420 extends into the reflector 300. The light emitted by the light source 420 is reflected upwards by the reflector 300, refracted by the optical lens 200, and processed by the anti-glare shield 100 before being transmitted to the surrounding environment. This structural design ensures the normal operation of the optical device, providing users with an effective lighting solution. The optical components are detachably connected to the fixed bracket 410, allowing for quick replacement of faulty or different specifications of optical components without complex operations, thus improving the maintainability of the optical device. When optical components need replacement or maintenance, they can simply be removed from the fixed bracket 410 without extensive disassembly of the entire optical device. The installation and replacement of optical components are facilitated by rotating and fixing them to the fixed bracket 410, further enhancing the convenience of replacing optical components and reducing maintenance costs and difficulty.

[0054] In this embodiment, a plurality of fixing hooks 301 are fixedly connected to the bottom end of the outer wall of the reflector cup 300, and the fixing bracket 410 is provided with hook grooves 411. The number of fixing hooks 301 and hook grooves 411 are the same and correspond one-to-one. The optical component can rotate relative to the fixing bracket 410 in the vertical direction, so that the fixing hooks 301 and hook grooves 411 are rotated and locked together. Specifically, there are two fixing hooks 301, which are evenly distributed at intervals on the outer wall of the reflector cup 300.

[0055] The fixing hook 301 at the bottom of the outer wall of the reflector 300 engages with the hook groove 411 on the fixing bracket 410 through rotation. This rotational fixing method allows the optical component to be quickly and securely fixed to the fixing bracket 410, ensuring the connection stability between the optical component and the fixing bracket 410 and preventing the optical component from loosening or falling off due to vibration or external force during use. Furthermore, when the optical component needs to be replaced, it can be simply rotated out, making the operation simple and quick without the need for additional tools. This further improves the efficiency of optical component installation and maintenance, highlighting the advantage of quick optical component replacement and enhancing the user experience.

[0056] The bottom of the outer wall of the reflector cup 300 is also fixed with several anti-recoil groove protrusions 302. The fixed bracket 410 is also provided with anti-recoil grooves 412. The number of anti-recoil grooves 412 and anti-recoil groove protrusions 302 are the same and correspond one-to-one. The anti-recoil grooves 412 are designed with sloping protrusion structures.

[0057] In this embodiment, the fixed hook 301 rotates clockwise, causing the fixed hook 301 to rotate and engage with the hook groove 411, thereby fixing the optical component to the fixed bracket 410 in the vertical direction; at the same time, the anti-retraction groove protrusion 302 rotates clockwise from a gentler section of the slope of the anti-retraction groove 412 to a section of the slope of the anti-retraction groove 412, so as to prevent the optical component from being easily rotated out counterclockwise.

[0058] For example, the optical lens 200 includes a transmissive lens, a refractive lens, an internal total reflection lens, a Fresnel lens, or a lens.

[0059] This versatility allows the optical device to select the appropriate optical lens 200 according to different usage scenarios and optical requirements, thereby achieving different optical effects to meet diverse market demands. Users can flexibly replace the optical lens 200 according to actual needs, improving the product's applicability and functionality.

[0060] like Figures 1 to 3 As shown, in one embodiment of this example, the anti-glare structure 110 is placed outside the mounting groove. For example... Figures 4 to 6 As shown, in another embodiment of this example, the anti-glare structure 110 is placed in the mounting groove.

[0061] The anti-glare structure 110 can be placed either inside or outside the mounting slot. This flexible installation method adds flexibility and variability to the design and use of optical devices, allowing users to choose whether to place the anti-glare structure 110 inside or outside the mounting slot according to actual needs, in order to adapt to different usage environments and design requirements.

[0062] When the anti-glare structure 110 is placed outside the mounting slot, the anti-glare cover 100 can be exposed outside the protective component, serving as an aesthetic decoration to enhance the appearance and aesthetics of the optical device; when the anti-glare structure 110 is placed inside the mounting slot, the protective component can provide a certain degree of protection for the anti-glare structure 110. Users can make reasonable choices according to different application scenarios to meet diverse usage needs.

[0063] like Figures 1 to 3 As shown, further, with the anti-glare structure 110 placed outside the mounting groove, the protective component includes a base 430. The top of the base 430 has a first storage groove with an upward opening. The bottom of the first storage groove is connected to the top of the mounting groove. The assembly structure 120 is matched and installed in the first storage groove.

[0064] The assembly structure 120 is fitted into the first storage slot, which makes the connection between the optical components and the protective components more stable, ensures the accurate positioning of the optical components within the protective components, prevents them from shaking or shifting during use, and thus reduces changes in optical performance, ensuring the stability and reliability of the optical device. At the same time, the first storage slot protects the assembly structure 120 from external impacts and damage, extending the service life of the optical components.

[0065] like Figures 4 to 6 As shown, further, with the anti-glare structure 110 placed outside the mounting groove, the protective component includes a lamp housing 440. The top of the lamp housing 440 is provided with a second storage groove with an upward opening. The bottom of the second storage groove is connected to the top of the mounting groove. The end of the anti-glare structure 110 away from the assembly structure 120 is bent outward to form a bent portion, which is matched and installed in the second storage groove.

[0066] The design of the bent portion fitting into the second storage slot enhances the overall appearance of the optical device, making the connection between the optical components and the lamp housing 440 tighter and more aesthetically pleasing, thus improving the overall integrity and consistency of the optical device. Simultaneously, the fit between the bent portion and the second storage slot provides a certain degree of sealing, preventing dust, moisture, and other impurities from entering the optical device, protecting the optical components and light source 420, ensuring the normal operation of the optical device, improving its overall performance and appearance quality, and extending its service life.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
